Struct Switch 

pub struct Switch {
    pub action: SwitchAction,
    pub condition: SwitchCondition,
    pub word: Word,
}

Parameter expansion modifier that conditionally substitutes the value being expanded

Examples of switches include +foo, :-bar and :=baz.

A switch is composed of a condition (an optional :), an action (one of +, -, = and ?) and a word.

Fields

action: SwitchAction

How the value is substituted

condition: SwitchCondition

Condition that determines whether the value is substituted or not

word: Word

Word that substitutes the parameter value

Trait Implementations

impl Clone for Switch

fn clone(&self) -> Switch

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Switch

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Switch

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Switch

fn eq(&self, other: &Switch) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Unquote for Switch

fn write_unquoted<W: Write>(&self, w: &mut W) -> Result<bool, Error>

Converts self to a string with all quotes removed and writes to w.

fn unquote(&self) -> (String, bool)

Converts self to a string with all quotes removed.

impl Eq for Switch
